Análise das causas e recuperação de fissuras em residência unifamiliar em Desterro-PB.

Abstract

Any structure is subject to the development of pathological manifestations, either because of its natural degradation throughout its useful life, or because of mistakes made during some of its stages, namely: design, execution and maintenance. In the case structures, the most common manifestations are cracks. However, cracks can manifest themselves through different origins. In this sense, this research had the general objective of identifying and analyzing the main causes of crack formation and indicate the main techniques for treating them in a residential building. To achieve the proposed objective, a case study was carried out in a residence located in the center of the city of Desterro-PB. It was noted the absence of execution of lintels and counter lintels, retraction of the laying mortar and hygroscopic movements. Thus, it was found that the cracking process identified in this building was caused by the absence of projects and errors in the execution phase. Without any technical or normative recommendation, the building was built based on knowledge based on empirical knowledge.
